Struct DsfbObserver 

pub struct DsfbObserver { /* private fields */ }

The DSFB observer for a single residual source channel.

For multi-channel observation (e.g., monitoring latency + throughput + heartbeat RTT simultaneously), create one DsfbObserver per channel and correlate their outputs externally.

Implementations

impl DsfbObserver

pub fn new(source: ResidualSource, config: &ObserverConfig) -> Self

Create a new observer for the given source channel.

pub fn with_heuristics( source: ResidualSource, config: &ObserverConfig, heuristics: HeuristicsBank, ) -> Self

Create an observer with a custom heuristics bank.

pub fn set_envelope(&mut self, envelope: AdmissibilityEnvelope)

Set the admissibility envelope (e.g., after regime classification).

pub fn set_static_priors(&mut self, static_priors: StaticPriorSet)

Replace the static priors used during heuristic matching.

pub fn observe_adapted<T, A>( &mut self, adapter: &A, input: &T, ) -> ObservationResult

where A: TelemetryAdapter<T>,

Adapt and observe one application-specific telemetry record.

pub fn observe(&mut self, sample: &ResidualSample) -> ObservationResult

Process a single residual sample and return the full observation result.

This is the primary API. It accepts an immutable reference to a sample and returns a complete structural interpretation.

Non-Interference

The sample is accepted as &ResidualSample. No mutation of the sample or its originating system is possible through this API.

pub fn grammar_state(&self) -> GrammarState

Current grammar state.

pub fn observation_count(&self) -> u64

Total observations processed.

pub fn audit_trace(&self) -> &AuditTrace

Reference to the audit trace.

pub fn current_episode(&self) -> Option<&Episode>

Current open episode, if any.

pub fn reset(&mut self)

Reset the observer state. Used on system restart or phase transition.

pub fn source(&self) -> ResidualSource

Source channel this observer tracks.
